Reboot and you're ready to go. 

Blackbird is simple to use, but also very powerful, doesn't give you an easy choice over which changes to apply, doesn't tell you exactly how it's implementing each change, and can only restore Windows default settings, not your original configuration.

What's new in v1.0.79 (see full changelog for more)?

- Fixed boot problems caused by disabling UPFC.exe on older versions of Windows 10. My bad, shit happens :/ 
- Fixed Xbox services not properly enabled when using the /X switch.
- Fixed some services not getting turned back on when using Blackbird's Recovery mode to restore default settings.
